摘要:
Video data and audio data of multiplexed data are separated. Abstract video data is generated from the separated video data and abstract audio data is generated from the separated audio data. Then, the abstract video data and the abstract audio data are packed and a packed video and audio data management table is generated from packed video and audio data D2 and video and audio data synchronization information D3. The packed video and audio data management table comprehensively manages the packed video and audio data. Thus, data of various video formats, various audio formats and various multiplexing formats can be monistically managed.
摘要:
A digital data transmitting apparatus including a reproducing device classifies serial packet data that are read at a variable rate from a digital data medium and demodulates into at least picture data, audio data and other data, an MPEG transport stream (MPEG-TS) generating device generates an MPEG-TS based on the digital data, and a digital interface device converts the generated MPEG-TS into digital transmission data and transmits the digital transmission data at a predetermined transmission rate. A digital data receiving apparatus including a digital interface device is operable at a predetermined transmission rate, a digital data receiving device receives digital data via the digital interface device, an MPEG-TS reproducing device reproduces an MPEG-TS from the received digital data, a reproducing device classifies the reproduced MPEG-TS into at least picture data, audio data, and private data, and a control device controls the reproducing device based on the private data.
